A "RoRo bin" typically refers to a Roll-on/Roll-off bin or container. "RoRo" stands for "Roll-on/Roll-off," a shipping and transportation term used for vehicles and cargo that can be driven onto and off a vessel, trailer, or platform. In the context of bins or containers, "RoRo bin" would suggest a container that allows for the easy loading and unloading of materials by rolling them on and off, as opposed to being lifted by a crane or other equipment.

These bins are often used in waste management, construction, or any situation where there's a need for efficient loading and unloading of materials or goods. They are designed with accessibility in mind, enabling easy transportation of items without the need for additional lifting equipment.
